1. Читання, переклад та обговорення тексту. Computer Virus

A computer virus is a computer programthat can replicate itself and spread from one computer to another. The term "virus" is also commonly, but erroneously, used to refer to other types ofmalware, including but not limited toadwareandspywareprograms that do not have a reproductive ability.

Malwareincludes computer viruses,computer worms,ransomware,trojan horses,keyloggers, mostrootkits,spyware, dishonest adware, maliciousBHOsand other malicious software. The majority of active malware threats are usually trojans or worms rather than viruses.^[2] Malware such as trojan horses and worms is sometimes confused with viruses, which are technically different: a worm can exploit security vulnerabilitiesto spread itself automatically to other computers through networks, while a trojan horse is a program that appears harmless but hides malicious functions. Worms and trojan horses, like viruses, may harm a computer system's data or performance. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious or simply do nothing to call attention to themselves. Some viruses do nothing beyond reproducing themselves.

Classification

In order to replicate itself, a virus must be permitted to execute code and write to memory. For this reason, many viruses attach themselves to executable files that may be part of legitimate programs (see code injection). If a user attempts to launch an infected program, the virus' code may be executed simultaneously. Viruses can be divided into two types based on their behavior when they are executed. Nonresident viruses immediately search for other hosts that can be infected, infect those targets, and finally transfer control to theapplication programthey infected. Resident viruses do not search for hosts when they are started. Instead, a resident virus loads itself into memory on execution and transfers control to the host program. The virus stays active in the background and infects new hosts when those files are accessed by other programs or the operating system itself.
